Abstract: The shelf life of polyurethane polyol pre-blends containing halogenated olefins is extended by encapsulation of active components such as catalysts and/or surfactants. The active component is encapsulated in a crystallizable or thermoplastic polymer. The encapsulated particles have a size of 2,800 microns or less and the active components are not significantly leaked out, particularly in the presence of halogenated olefins.

Abstract: A fluorination catalyst such as a chromium oxide-based fluorination catalyst may be activated or reactivated by contacting the catalyst. with a source of reactive fluorine, for example nitrogen trifluoride (NF3) or fluorine (F2). Fluorinated compounds may be prepared by the gas phase reaction of hydrogen fluoride (HF) with various substrates such as chlorinated compounds. A number of metal oxide-based catalysts have been developed for this purpose.

Abstract: A method of separating a composition containing at least one organofluorine compound from at least one inorganic compound by contacts the composition with a semipermeable membrane. Other methods separate a organofluorine compound from a composition containing at least one other organofluorine compound or chlorocarbon. Methods also include isolating a single organofluorine compound from a composition comprising a mixture of organofluorine compounds, chlorocarbons, and/or inorganic compounds.
